I check when I'm syncing in iTunes, usually each morning.
If you click on the Apps icon in the list of apps that have updates it brings you to the Apps description page that lists the details of the update.
I don't. I wait until I plug it into iTunes and iTunes shows that there are updates. I really wish there was a way to read the update description in iTunes.
